lhe above described operations are then repeated with the successive sheets or plates operated upon, the slitting rollsor disks heing adjusted as is necessary, with a change in thickness' or gage of. the, materials being cut, and the cutting disks being adjusted lengthwise on the screw threaded shafts as becomes necessary in making the strips of the desired width.A i

The advantages of my invention Will be apparent to those skilled in the art. By employing a series of staggered feed-in rollers instead of a pair or series of pairs of rolls in which, the axes of the top and bottom rollers of each pair are in the same vertical plane, the plates or. sheets to-be cut have a surface contact with the feedin rollers instead of a line contact by causing surface contact between the sheets and rollers, and the dilliculty' of preventing cutting of the strips in a curvec ,line instead of in the desired straight line as overcome. The feed-in rollers also actflattening rollers to remove any buckles in the sheets or plates.

Modifications in the construction and arrangement of parts may be made without departing from myl invention as deiined in the appended claims. The threaded shafts for the slitting rolls may be replaced by Unthreaded shafts, the number of cutting disks on the shafts may he varied, and other changes may he made.
